1SS400SMT2R from ROHM Semicon, in a SOD-523. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode, marked by the bar on the package; the diode withstands VR 80 V (VRM 90 V) reverse voltage and IR max 100 nA at VR=80 V. |
| 2 | A | passive | Anode; average rectified forward current Io is 100 mA (IFM 225 mA, IFSM 500 mA for t=1s) and VF max is 1.2 V at IF=100 mA. |
